#176 inconsistency .incSml. code versus docs

[Gert Van den Eynde]

Hi,

In the docs on the web I read on set y axis:

`set y axis .bottom. .top. .incBig. .incSml.' Make y-axis range from
`.bottom.' to `.top.', with labelled increments at `.incBig.', and small
tics at `.incSml.' NOTE: if the axis is logarithmic, the value of
`.incSml.' takes on a special meaning: if it is positive then small
tics are put at values 2, 3, 4, etc. between the decades, but if
`.incSml.' is negative then no such small tics are used.

However, when I want to set .incSml. to a negative value because
I don't want small tics, I get the error

ERROR: `set y axis .bottom. .top. .incBig. .incSml.' cannot have
non-positive .incSml. value for logarithmic axis
Bad command: `set y axis 1.0e-105 1.0e-05 20 -1'

Proopsed patch:

In set.cc remove lines 2881-2882 and 3370-3371 or change the
docs

bye,
